Description

Solar automatic dust removal and cooling system

Technical Field

The utility model relates to a solar protection system, specifically speaking are automatic dust removal cooling system of solar energy.

Background

At present, the use of civil solar photovoltaic power generation devices is more and more popular, but in northern areas of China, the dust accumulation phenomenon on the solar photovoltaic panel erected outside or on the roof is very serious because the pollution degree of particles in the air is large. The accumulated dust on the solar photovoltaic panel seriously influences the photoelectric conversion efficiency of the solar photovoltaic panel. In order to remove the accumulated dust and floating dust on the solar photovoltaic panel, the solar photovoltaic panel can be washed in a water pipe spraying and flushing manner in a conditioned place; places without conditions can only adopt the crude method of water lifting and washing.

In addition, the photoelectric conversion efficiency of the solar photovoltaic panel is reduced at the overheated ambient temperature in summer, and the existing solar photovoltaic panel does not have facilities and capability for automatically cooling in summer.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automatic dust removal cooling system of solar energy to solve the difficult problem of cleaing away and can not cool down by oneself summer of deposition floating dust on the solar photovoltaic board.

The utility model discloses a realize like this: the utility model provides an automatic dust removal cooling system of solar energy, includes:

the spraying pipe is transversely arranged at the top of the solar photovoltaic panel, and a plurality of spray heads facing the surface of the solar photovoltaic panel are connected to the pipe body and used for spraying water on the surface of the solar photovoltaic panel to remove dust and/or cool the solar photovoltaic panel;

the water supply pipeline is vertically arranged, one end of the water supply pipeline is communicated with the spray pipe, and the other end of the water supply pipeline is downwards inserted into the water storage tank and used for conveying spray water;

the water storage tank is arranged underground or on the ground surface near the solar photovoltaic panel and is used for storing spraying water;

the supercharging device is arranged on the water supply pipeline or in the water storage tank and is used for pressurizing and conveying water in the water storage tank into the water supply pipeline;

the check valve is arranged on the water supply pipeline above the supercharging device and used for preventing water fed into the water supply pipeline from flowing back;

one end of the water return pipe is inserted into the water storage tank, the other end of the water return pipe is connected with a tee joint which is arranged on the water supply pipeline and is positioned above the one-way valve, and the water return pipe is connected with a water release valve; and

and the electric control cabinet is used for starting the supercharging device to work for a set time period at fixed time or when the temperature of the solar photovoltaic panel exceeds a set temperature.

The utility model discloses utilize supercharging device to pass through the water supply pipe with the water in the storage water tank and pressurize to the shower, the rethread shower nozzle with water spray to the face of solar photovoltaic board on to clear away deposition and the dust floating on the solar photovoltaic board, solved the inconvenience that relies on manpower to bring with water pipe or cask brush-sprayer from this, and still can be in annual spring, summer, autumn three seasons, through spraying the washing, with the temperature reduction of solar photovoltaic board. Because dust removal and cooling are timely, the reduction of the photoelectric conversion efficiency of the solar photovoltaic panel can be effectively prevented, and the generated energy can be improved by 30-40% compared with the solar photovoltaic panel in an artificial dust removal state. For the dust removal operation of the solar photovoltaic panel in winter, after accumulated dust is removed, a drain valve on the water return pipe can be opened in time, so that accumulated water remained in the spray pipe and the water supply pipeline can smoothly flow back into the water storage tank, the freezing and cracking phenomenon of the pipeline in the system is avoided, the system can be used repeatedly, and the failure rate is reduced.

The utility model discloses an installation is used, has avoided solar photovoltaic board maintainer's climbing to climb down, has simplified solar photovoltaic board's dust removal operation to have the efficiency for the cooling of solar photovoltaic board, still saved the operation manpower simultaneously, be suitable for popularization and application.
